Era Flip Tumblers are 100% leakproof with cold beverages and iced carbonated beverages when in the locked position. A 50% ice to liquid ratio is recommended when using carbonated beverages.



Not recommended to be used in the locked position with hot beverages as pressure will build up and hot liquid may expel from the from the tops or sides. Using hot beverages with a straw poses a scalding risk.
